UNITED STATES OIL-WELL STRAINER.

Application filed October 25., 1922. Serial No. 596,824.

lstrainer for oil wells, and has for its object to produce a strainer for this purpose made up of any desired number of 4sections of apertured tubular members having a heavy coating of Monel metal to render the same acid-proof and non-corrosive, in combination with tubular mineralized animal and vegetable fiber woven cloth which is acid resisting to strain the fine sand, which in the coastal field is commonly knownas beach sand, the tubular fiber being enclosed in a. comp'aratively finely reticulated tube which is also coated with heavy Monel metal or other acid and rust-proof metal, and as a consequence to produce a strainer which shall be long lived, in which the liability of rust erosion from the action of salt w'ater is overcome and the collapse of the' device is thus effectively prevented.

To the attainment of the foregoing and other objects which will present themselves as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this application.

In the drawings Figure 1 .is a side elevation of the improvement.

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Figure 3 is a sectional view on the line 3 3 of Figure 1.

Figure 4 is a fragmentary perspective view of the heavy tube employed.

Figure 5 is a similar view of the corrugated and reticul'ated tube employed.

Figure 6 is a view similar to Figure 2, but illustrating a modification.

Figure 7 is a sectional view on the line 7-7 of Figure 6.

As disclosed by the drawings I make use of any desired number of heavy iron tubes 1, each of which having its upper end provided with a hub 2 and a flange 3 projecting inwardly of the hub to provide therewith a pocket for the straight end of the next connected tube. Each tube is provided with comparatively' large openings 4, the

same being arranged in vertical series and in staggered relation with respect to each other. The tubes 1 have a heavy coating of Monel metal totiender the same acid-proof or nony corrosive.

In one form of the invention I arrange upon the exterior of the tubes 1 tubular mineralized animal or vegetable fiber woven cloth 5 treated to render the same acid-resisting and designed to prevent the ine sand entering the openings 4 in the tubes 1. Around the fiber tubes 5 I arrange comparatively heavy and also comparatively closely apertured tubes 6. These tubes may be provided, as shown in certain figures of the drawings, with preferably equi-distantly spaced annularly disposed ouwardly bulged portions 7 designed to catch the sand before the same contacts with the fiber tubes 5, and also designed to serve as pockets for the sand which enters the said bulged or corrugated portions. The tubes 6 are heavily coated with Monel metal or any other acid and rust-proof metal so that the strainer will not be affected by salt Water or other agents that cause the collapse of strainers of this character. The fiber tubes 5 provide a filtering medium for the tubes 1 and 6 as well as a packing for the said metal tubes.

I may find it desirable to remove the fiber tubes 5, and the outer tubes 6 for the cleaning of the same, and therefore I have illustrated in certain figures of the drawings connected tubes 8 similar to the tubes 1, and have arranged therein a pair of spaced tubes 9 and 10 similar to the tubes 6. These tubes may have their lower ends connected together and preferably threadedly engage the tubes 8. Between the tubes 9 and 10 there are fabric tubes 11 similar to the fabric tubes 6.

.The tubes 9 and 10 being connected together, and being tlneadedly engaged with the tubes 8 permit of the removal ofthe strainer tubes 9 and 10 and the fiber packing between the tubes so that these elements may be cleaned and replaced, when desired. Of course, a suitable tool is employed for connecting the tubes 9 and 10 to the tube 8 and for removing and lifting the same from the said tube 8, but as any desired means may be employed for this purpose, I have not deemed it necessary to illustrate the same.

It is thought that the foregoing description, when taken in connection with the drawings will fully set forth the construc- PATENT orales.

.tion and advantages of my improvement to those skilled in the art to which this invention relates, so that further detailed description will not be required. t

Having described ther invention, I Clil'lZ-r An oil Well strainer constructed of heavy iron tube sections which arecoated with an acid-resisting substance and having spaced openings therethrough, each of saidv tubes having of the next tube thereon for connecting'the tubular sections, other apertured tube seca hub at one end receiving the end'- tions surrounding the first mentioned section and held thereon by the confrontingr base and mouth of the hubs of said first mentioned tube sections and Woven fiber tubes of acid-resisting material arranged between the joints of the first mentioned tube sections and the metal tubes on said sections, and said fiber tubes providing a packing as Well as ltering medium for said inner and outer metal tube sections.
